Abstract: IN THE CANADIAN PATENT OFFICE                November 3, 1980 Inventors: Clyde C. Grady, 11 Clyde C. Grady Title: "Concrete Molding Machine" Abstract:     A molding machine is disclosed which can be used in the man-ufacture of concrete building elements.  A method for the molding of concrete building elements is also provided.  The molding machine is constructed of vertical walls joined to form a single outer frame which is moveable up and down by means of expandable joints such as pneumatic or hydraulic cylinders which allow positioning and vibration of the outer frame.  To said outer frame are attached horizontally expandable joints which support at least two mold sides which can be placed in abutment by the action of the expandable joints so as to form the continuous sides of a mold. The bottom side of the sequentially assembled mold is provided by a metal plate to which the aforesaid sides are lowered or attached.  Detachment of the mold sides from the said outer frame as a unit allows support of the uncured concrete by the mold sides as an assembled mold during subsequent transport from the molding machine to curing ovens.  The outer frame may then be used to assemble another set of mold sides immediately and is not prevented from use until the cementitious material which filled a prior set of mold sides cures sufficiently for the removal of the mold sides.  Provision is also made for the sup-port of articles to be cast internally in the building elements by means of members attached at one end to the vertical walls of said outer frame, wherein the members may be extended hori-zontally thru apertures in the mold sides to within the confines of the various molds by a means of  expansion and contraction which forms an integral part of the said members.

Abstract: ATOMIZING AIR METERING NOZZLE                 ABSTRACT OF THE DISCLOSURE          A nozzle is provided for a gas turbine combustion system in which the atomizing air metering nozzle is provided with an aerodynamically rotating orifice which turns air flow radially inward toward the source or oil or other liquid fuel prior to initiating a swirling vortex to eliminate centrifuging action of the air stream within the nozzle.  Metering on the atomizing air vortex generating vanes are located at the exit of the vanes near the outer face of the fuel nozzle to eliminate entrapment of airborne particles.  Vortex generator vanes are provided in the air stream path;  these vanes lie on the surface of a cone which converges toward the nozzle exit.  The vanes are at an angle to lines which would lie in a plane through the axis of the aforementioned cone along with the surface of the cone, thereby to form a swirling air vortex at the nozzle exit.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to the production of vinyl dispersion or paste resins by means of the emulsion polymerization process and the recovery of the resins from the polymer latices produced thereby.  In the process, the polymer latex is first carefully coagulated to yield a fast filtering sludge, the sludge is passed to a pressure filter to separate a high solids, friable polymer wetcake from the serum, the wetcake is rinsed with proper agents to neutralize the same and remove undesirable residues, pressure in the filter is applied to the rinsed wetcake to increase the solids content thereof, the wetcake is then broken into particles and friable agglomerates, and thereafter said particles and agglomerates are dried and ground to proper size in one step in a fluid energy mill.  Thus the spray drying and the subsequent harsh grinding steps are eliminated producing a superior product for plastisols.

Abstract: ABSTRACT      A bit synchronizer for T-4 fiber optic data communication environments is configured of an input buffer amplifier to which the data to be regenerated is applied.  The input buffer provides isolation between upstream signal processing circuitry and a bit rate generator coupled to the output of the buffer.          Also coupled to the buffer output is a bit decision circuit essentially configured of a limiter and output flip-flop.  The bit rate generator employs a limiter and dual delay logic cir-cuitry connected in series that provide a strong bit rate com-ponent which is phase coherent with the input NRZ data transi-tions. Unwanted baseband components are removed by a bandpass filter the output of which, as the output of the bit rate generator, is coupled to a phase locked loop from which a crys-tal oscillator clock synchronized with the data transitions is produced 'o clock the output flip-flop in the bit decision cir-cuit.  Interposed between the output of the crystal oscillator and the clock control input of the output flip-flop is a delay circuit which is set to adjust the clock timing to mid-bit of the limiter.  The regenerated data is derived from the Q output of the flip-flop.

Abstract: ABSTRACT           In prior art filters using CTD (charge transfer device) lines and having relatively narrow band widths, the capacitance ratios of the CTD lines employed differ significantly, which leads to difficulties with respect to tolerances in the manu-facturing process.  The present invention provides a CTD line consisting of a plurality of CTD elements with which one obtains any random division ratio without the influence of the tolerances having a negative influence at the same time.  The CTD line has a plurality of CTD elements with separating ridges for charge division oriented in the direction of charge transport, the ridges being applied as thick oxide ridges or channel-stop regions.  The separation ridges for successive stages are disposed to yield a charge division in the ratio of approximately 1:1.  A plurality of summation sections are provided between the division stages, all remaining partial charges with the exception of only one partial charge being summed in the summation sections.

Abstract: ABSTRACT OF THE DISCLOSURE    An inspection device for an apparatus for inspecting objects, such as glass bottles and the like, for defects includes an interface circuit connected between a source of data signals and means for processing information obtained from the object.  The interface circuit receives the data signals, typically in digital series form from a photodiode camera and light source, and includes a latch for storing one of the digital signals, a pair of adders, and a storage means for a plurality of threshold signals.  Each data signal is compared to the preceding data signal stored in the latch in one of the adders to generate a difference signal representing the difference in magnitudes between the two signals.  Each difference signal is compared with a selected one of the stored threshold signals in the other adder to generate an event signal representing the difference in magnitudes between the two signals.  The means for processing information includes a pair of control units and a master control means for alternately connecting the control units to the interface means, whereby one of the control units is receiving a group of the event signals representing one object while the other control unit is processing a preceding group of the event signals.  Signals are also generated to identify the location of each event signal with respect to a corresponding photodiode and to identify during which vertical sweep of the object the event signal was generated to associate the event signal with a point on the object,  The event signals are processed to identifiy defects.  Events in proximity in the same sweep are identified as a string.  Event magnitudes and totals in a string are compared with predetermined values to identify defects.  Strings in proximity are identified as a blob.          Event magnitudes and totals and blob width are compared with predetermined values to identify defects.  The event signals can be displayed as a two-dimensional representation of the surface of the object, as if it had been cut and unwrapped.          The operator can repeat the inspection utilizing different threshold values to optimize the defect detection performance of the inspection device.  If the storage means is disabled and the threshold signals magnitudes are set at zero, the data signals will pass through to be displayed as the data signal magnitudes on one orthogonal axis and the Location of the associated points on the other axis.
